Abstract

Cette invention se rapporte aux techniques de fabrication d'éléments polymères et concerne un procédé de production de micro-lentilles polymères ayant des surfaces de réfraction planes et sphériques ou asphériques, ces lentilles étant solides ou creuses, et possédant une répartition axiale et/ou radiale uniforme ou gradiante de l'indice de réfraction. Cet élément polymère est obtenu de la manière suivante. On place dans une cuvette contenant une solution tampon stationnaire (2), un dispositif de maintien sur lequel se trouvent un ou plusieurs substrats (3). A la surface du substrat, on dépose, à l'aide d'un doseur, une goutte d'une taille voulue d'une composition organique photosensible. Cette composition ne peut se mélanger à la solution tampon et possède une densité supérieure à celle de ladite solution. On obtient ainsi un élément stable dont la forme et les conditions de formation sont fonction de l'équilibre des forces qui s'exercent sur lui. Les substrats peuvent avoir une forme plane, courbe ou périodique, et peuvent être hydrophiles ou hydrophobes, réfléchissants, métalliques, vitreux, polymères, et ceci avec ou sans chauffage. La goutte formant l'élément est soumise à l'action d'un rayonnement jusqu'à sa solidification complète sur le substrat de manière à obtenir un élément fini. Les parois de la cuvette et la solution tampon sont transparentes de manière à laisser passer ce rayonnement. Après avoir été soumis au rayonnement, les éléments polymères (4) peuvent être soumis à une terpolymèrisation complémentaire, puis sont séparés du substrat, rincés, séchés et soumis à un traitement thermique de manière à minimiser les tensions internes résiduelles. Des revêtements anti-réfléchissants et protecteurs, ou encore des revêtements photo-anisotropiques, photochromiques ou autres peuvent être appliqués à la surface de l'élément.
